applications. For gait measurements the configuration must be set to the values  indicated 
below, otherwise the software cannot analyse the data.

The two sensors must also be synchronised together, therefore one of the sensors should 
store  an empty text  file called “slave.txt”  which indicates that it is the “slave” sensor, the 
second  sensor  does  not  have  such  a  file  and  is  thus  the  “master”  sensor.  The  correct 
configuration is pre-installed when you order a PhysiGait Lab, so you don't need to modify 
the configuration of the Physilog®5.

 

 5.3  

How to update the software on USB key 

The software on the USB key can be updated to the latest version using the “Gait Analyser 
Updater”  which  can  be  downloaded  for  free  from  www.gaitup.com/support.  Install  the 
updater software on your computer, start the updater software and plug your USB key with 
PhysiGait Lab software. By following the instructions provided by the software, your USB 
key will automatically be updated with the latest software version. The computer needs to 
be connected to the internet to download the new version. Free updates are included in the 
first  year  after  purchase,  for  later  updates  an  extension  can  be  purchased.  If  the  update 
doesn't  work,  please  contact  Gait  Up's  customer  service  (via  contact  form  on 
www.gaitup.com/support or via email[email protected]). 

 5.4  

Handling / Maintenance  

Physilog®5 should be handled carefully. In particular, it should not receive shocks, such as 
fall, crushing, being hit etc. Do not press forcefully on the on/off button, this can damage the 
button.  
 

Warning:

  Do  not  use  or  charge  the  Physilog®  if  the  sensor  or  its  case  is 

damaged. Contact Gait Up about what further action is needed when the case 
is  damaged.  In  case  the  battery  is  damaged  immediately  move  the  device 
away from flammable materials and contact Gait Up's customer support. 

 

Sensors  can  be  placed  on  the  foot  in  any  orientation,  it  will  not  influence  gait 
measurements  

 

To  benefit  from  the  maximal  battery  life,  fully  charge  Physilog®  sensors  before  doing 
measurements (LED shines green when connected to computer or charger, you can also 
check the battery level with the Physilog®5 companion Android Application available on
